Abstract
The invention discloses a chain transmission device for a rock drill and relates to the technical field of auxiliary equipment of hydraulic rock drills. The chain transmission device comprises an oil pipe of which one end is connected with an impact device and a driving chain used for driving the impact device to reciprocate, wherein the head end and the tail end of the driving chain are connected with an impact device mounting seat; the other end of the oil pipe bypasses a roller carrier and then is fixed on a propelling beam; the roller carrier is driven by a climbing chain wheel to reciprocate on the propelling beam; the upper part of the climbing chain wheel is meshed with the driving chain, and the lower part of the climbing chain wheel is meshed with the climbing chain; the climbing chain is fixed on the propelling beam. Compared with the prior art, the chain transmission device has the advantages that wherever the impact device slides to, the oil pipe is always exactly wound on the roller carrier, that is, the total length from the impact device to the roller carrier and to the connecting part of the oil pipe and the propelling beam is not changed, so that no redundant oil pipe drops off, and the oil pipe cannot be in a tightened state.
Description
Technical field
The present invention relates to hydraulic gate auxiliary device technical field, the chain and sprocket driving device of especially a kind of rock drill.
Background technology
Hydraulic gate is operationally, it is necessary to hydraulic oil provides impulse force to impacter; When feeding motor drive chain time, impacter slides up and down along forward beam under the pulling force of chain, and is connected with impacter for providing hydraulic oil pipe one end of hydraulic oil to be fixed on forward beam, the other end along with impacter slip. Owing to the sliding scale of impacter is relatively big, in order to ensure that oil pipe is not at tensioned state, then it is necessary that oil pipe has enough length when impacter distance oil pipe fixing point is farthest. So, exist for following problem: when impacter distance oil pipe fixing point is nearest, owing to oil pipe is long and cause tenesmus so that oil pipe is in suspension status, not only affects attractive in appearance, and, oil pipe tenesmus produces certain pulling force, have impact on the life-span of oil pipe. Therefore, it is necessary to a kind of device of design, making oil pipe be looped around above, no matter which position impacter slides into, and tubing length is all just suitable, had both been not at tensioned state, and had not also dropped because length is oversize.
Summary of the invention
The technical problem to be solved is to provide the chain and sprocket driving device of a kind of rock drill making oil pipe not only be not at tensioned state but also do not drop because length is oversize.
In order to solve the problems referred to above, the technical solution adopted in the present invention is: include the oil pipe that one end is connected and the driving chain that drive impacter is reciprocating and head and the tail two ends are all connected with described impacter mounting seat with impacter, the described oil pipe other end is fixed on forward beam after walking around rolling wheel support, and described rolling wheel support is driven reciprocating at described forward beam by climbing sprocket wheel; Described its top of climbing sprocket wheel is engaged with described driving chain, and its underpart is engaged on climbing chain, and this climbing chain is fixed on described forward beam.
In technique scheme, technical scheme is it may also is that described rolling wheel support is fixed in roller mounting seat more specifically, and described climbing sprocket wheel is fixed under described roller mounting seat by connecting axle.
Further: described driving chain is walked around the tightener sprocket being contained in described forward beam one end and is contained in the drive sprocket of the described forward beam other end;Described climbing sprocket wheel is between described tightener sprocket and described drive sprocket.
Further: described impacter mounting seat is provided with the support for fixing described oil pipe, being integrally fixed on the fixed support that described forward beam is provided with of described oil pipe.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, owing to one end of oil pipe is connected with impacter, the other end is fixed on forward beam after walking around rolling wheel support, rolling wheel support is driven reciprocating at forward beam by climbing sprocket wheel, climbing sprocket wheel is by driving chain-driving to walk, therefore, no matter which position impacter slides into, oil pipe is all the time right around on roller, namely, from impacter to rolling wheel support again to the length sum between oil pipe and forward beam junction be constant, so, both do not have unnecessary oil pipe to drop, and be unlikely to make oil pipe be in the state tightened yet.
2, after adopting the drive mechanism of the present invention, oil pipe not only arranges neatly, compact, attractive in appearance, and when following impacter and sliding up and down, is unlikely to rock because of oil pipe tenesmus, makes oil pipe be subject to extra pulling force, affect the life-span of oil pipe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the A place enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
The present embodiment as depicted in figs. 1 and 2, include oil pipe 6 and drive chain 2, one end of oil pipe 6 is connected with the support 5 of impacter 3, the other end is fixed on the fixed support 12 on forward beam 13 after walking around rolling wheel support 8, rolling wheel support 8 is fixed in roller mounting seat 10, and roller mounting seat is connected to climbing sprocket wheel 7 by connecting axle 10 times; The one end driving chain 2 is fixed on the upper end of impacter mounting seat 4, the other end walks around the tightener sprocket 1 being located at forward beam 13 upper end and the drive sprocket 9 being located at forward beam 13 lower end, turn round the lower end walking around climbing sprocket wheel 7 and impacter mounting seat 4 again to fix, between the loop checking installation of drive sprocket, parallel it is provided with a climbing chain 11, climbing sprocket wheel 7 lower end is engaged on this climbing chain, and climbing chain 11 is fixed on forward beam.
When drive sprocket 9 rotates, chain 2 is driven to drive impacter 3 to move, owing to driving chain 2 and climbing sprocket wheel 7 to engage, climbing chain maintains static, so when driving chain 2 to move, climbing sprocket wheel 7 makes pure rolling on climbing chain 11, the o1 point of climbing sprocket wheel 7 is instantaneous center of velocity, due to o1o2=2oo1, so the speed of o2 point is equal to 2 times of the speed of o point, that is to say 2 times equal to rolling wheel support 8 of the speed of impacter 3. During work, rolling wheel support 8 is equivalent to a movable pulley, owing to oil pipe 6 one end is connected on support 5, being then wrapped around on rolling wheel support 8, the other end is connected on fixed support 12, and the movement velocity of impacter 3 is equal to 2 times of rolling wheel support 8, so no matter where impacter 3 moves to, oil pipe 6 is all just looped around above rolling wheel support 8, has not both had the oil pipe of additional length to fall, and is also unlikely to make oil pipe be in tensioned state.
Tightener sprocket 1 act as the elasticity regulating chain, more smooth and easy when making chain drive.
